Given numbers are 690,238,874,396,803

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 690,238,874,396,803 is 7516513620.

Find LCM of 690,238,874,396,803 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 11 x 23 x 5 x 119 x 19 x 6 x 73 = 7516513620

Therefore, the lowest common multiple of 690,238,874,396,803 is 7516513620.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

690 x 238 x 874 x 396 x 803 = 45640270700640

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

238 : 1, 2, 7, 14, 17, 34, 119, 238

874 : 1, 2, 19, 23, 38, 46, 437, 874

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,238,874,396,803, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

238:2x 7x 17

874:2x 19x 23

396:2x 2x 3x 3x 11

803:11x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 11x 23 = 6072

Therefore, the value for common factors is 6072.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 45640270700640/(1x6072)

LCM = 45640270700640/6072

LCM = 7516513620

Thus, we can understand that the LCM of 690,238,874,396,803 is 7516513620.
